The Sierra Norte de Sevilla Natural Park forms a natural barrier for the humid Atlantic air that flow inland through the Guadalquivir valley. For this reason, annual rainfall is relatively high, between 600 and 800 mm. This said, climate in the Natural Park is classed as Mediterranean-continental, which means that temperatures vary more widely than Atlantic influenced weather, with night frost and an average winter temperature of 9º that increases to 25º in summer, with peaks of up to 40ºC.
